Jika sedang shalat, janganlah sekali-kali meludah di depan atau di sebelah kanannya, namun hendaklah ia meludah di sebelah kiri atau di bawah kakinya
Imam Ahmad : 4905حَدَّثَنَا يَحْيَى عَنْ عُبَيْدِ اللَّهِ أَخْبَرَنَا نَافِعٌ عَنِ ابْنِ عُمَرَ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ رَأَى نُخَامَةً فِي قِبْلَةِ الْمَسْجِدِ فَحَتَّهَا ثُمَّ قَالَ إِذَا كَانَ أَحَدُكُمْ فِي الصَّلَاةِ فَلَا يَتَنَخَّمْ فَإِنَّ اللَّهَ تَعَالَى قِبَلَ وَجْهِ أَحَدِكُمْ فِي الصَّلَاةِ
Narrated to us [Yahya] from [Ubaidullah] Narrated to us [Nafi'] from [Ibn Umar], that the Messenger of Allah sallallaahu 'alaihi wasallam saw phlegm in the direction of the Qibla of the mosque and he rubbed it, then he said: "When one of you is praying, let him not spit, because Allah Ta'ala is facing the face of one of you in prayer.
